他にも幾つかある。2. Description of the Related Art Generally, when a flat plate chain is used in combination with a finger transfer plate, a gap is created between the chain and the finger transfer plate. Due to this gap, the articles carried on the top surface of the chain often tilt and fall in the middle of transportation or hinder the progress thereof. To solve this problem, finger-shaped transfer plates have hitherto been used. A conveyor system using such finger-like transfer plates is disclosed, for example, in U.S. Pat. No. 4,051,949 (hereinafter referred to as the Lapeire patent). That is, the La Peyre patent addresses problems with this type of chain, such as flipping associated with string effects, and provides a way to minimize some of them. However, there are several other problems with this type of chain that are not addressed in the Lapeire patent.

上に巾の広い切欠部を設けなければならない。For example, in order to handle a large load, it is desirable to drive with a sprocket having relatively wide teeth. At the same time, to engage the chain with the finger-shaped transfer plate,
The top surface of the chain needs to be provided with cutouts along the width direction, but these cutouts must not be sized so as to tip over the articles carried by the chain. The link described in the Lapeire patent forms a drum-driven belt instead of a sprocket-driven chain.However, when the Lapeire-type chain is driven by the sprocket, the width of the sprocket teeth is changed to the top of the chain. Obviously, it cannot be wider than the width of the notch provided in the surface. Therefore, in order to use a wide tooth sprocket for the Lapeire patented chain, a wider cutout must be provided on the top surface of the chain.

It is a cross-sectional view in the 0-to-zero connection portion. Each tubular portion 26, 3
A pin 42 is inserted through the 0 hole 32 to connect the links 10. The pin 42 includes a shaft portion 44, a head 46 formed on one end of the shaft portion 44, and a head 48 fitted on the other end of the shaft portion 44. In the case of this embodiment, pin 4
2 is a thermoplastic resin. Prior to inserting the pin 42 into the opening 32, the pin 42 includes only a shaft portion 44 and a head 48. At the time of assembling the chain 36, the second hollow tubular portion 30 of each link has a space 2 between the first hollow tubular portions 26 of the adjacent links.
8 and then the shaft portion 44 is inserted into the opening 32 so that the head 48 receives the housing recess 5 of the outermost first hollow cylindrical portion 26.
It is fitted in 4. After that, the head 46 is formed at a predetermined position by ultrasonic processing, and is fitted into the storage recess 52 of the outermost first hollow cylindrical portion 26 at the other end. As a result, the pin 42 has the storage recesses 52, 54 of the outermost first hollow cylindrical portion 26.
Heads 46 and 48 respectively fitted in the The fact that the pin heads 46 and 48 are recessed means that
It has the following advantages. First, the head 46 does not wear due to friction with the supporting member of the adjacent conveyor. Secondly, as shown in FIG. 7, when several chains 36 are arranged side by side, a wide conveyor chain is constructed without causing interference of pin heads and increasing the gap between adjacent fork-shaped members 18. it can. A concave groove 50 is provided in the center of the outer surface of the head 46. Although not shown in the drawing, the head 48 also has a similar groove 50. These grooves 50 are used as a means for centering the drill blade when removing the pin 42. Therefore, after the head 46 is bored, the pin 42 can be easily removed by pushing the pin toward the head 48. If you want to prevent pin rotation and suppress contact wear , use the heads 46, 4
The pin 44 provided with 8 has a rectangular, hexagonal, or other cross-sectional shape, and the storage recesses 52, 54 have the same cross-sectional shape.
The heads 46 and 48 can be prevented from rotating.

As the sprocket 56 rotates clockwise, the articles carried on the top surface 12 of the chain 36 are transferred to the finger transfer plate 38. The fingers 40 of the finger-shaped transfer plate 38 are the centerlines 4 of the first hollow cylindrical portion 26.
1, the first hollow cylindrical portion 26 extends beyond the sprocket 5
The articles carried by the chain 36 are transferred onto the finger-like transfer plate 38 before they come into contact with 6 and before the chain 36 begins to bend around the circumference of the sprocket 56. At this time, it goes without saying that the chain 36 is driven by the sprocket 56 contacting the tubular portions 26 and 30.

Does not come into contact with. Also, the chain 36 is the sprocket 56.
When turning along the perimeter of an article, no fall of the article occurs for the following reasons. That is, firstly, the fork portion 20 is formed in each tubular portion 2
Since it does not extend beyond the center line 41 of the 6, 30, the forks 20 follow the circumference of the sprocket 56 according to the respective tubular parts 26, 30 and do not cause a fall. Second, the handle 22 extending beyond the centerline 41 has a curved top surface along the perimeter of the sprocket 56. For this reason,
The problem of falling when the top surface of the handle 22 is flat is avoided.

当接させることができる。FIG. 7 is a schematic view showing an example in which a large number of links 10 are connected to each other to form a large-sized chain along both the width direction and the length direction. Since the heads 46 and 48 are recessed, it is not necessary to pass each pin 42 over the full width of three links. By using all the short pins 42, or by using most of the short pins 42 as the long pins 42 and extending over a part of the entire width, it is possible to easily abut the three links integrally.

防ぐ効果がある。The effect of the present invention is to provide a chain that can be used in combination with a finger-shaped transfer plate, and to provide a chain with a tubular portion driven by the teeth of a sprocket, which is sufficient to withstand a large load. Generally, a flat plate chain is combined with a finger-like transfer plate by providing a strong chain, a chain that can be bent backwards, and a chain that has an open area sufficient for draining and ventilation of the chain. When used for a long time, the gap between the chain and the finger-shaped transfer plate is eliminated, and it is effective to prevent the articles carried on the top surface of the chain from tilting and falling during transportation and obstructing the progress thereof.
